Summary
Memorized information impacts visuomotor control, influencing grasping movements. Priming effects on movement initiation and grip depend on object orientation and prime completeness, suggesting task-specific brain pathway interactions.
Area of Science:
- Cognitive Neuroscience
- Motor Control
- Human Perception
Background:
- Memorized information, or primes, can influence real-time visuomotor control.
- Previous research shows primes affect grasping movements toward target objects.
Purpose of the Study:
- To investigate the generalizability of priming effects in visuomotor control.
- To determine if priming depends on target object orientation and prime-target similarity.
Main Methods:
- Examined priming effects with varying prime and target object orientations.
- Tested primes that were either identical to or only half of the target object.
- Measured initiation time and final grip orientation during grasping movements.
Main Results:
- Prime orientation influenced initiation time and grip orientation when the target object orientation allowed for a comfortable grasp.
- Priming effects on initiation time were observed only when the whole target object was used as a prime, not when only half was presented.
- Priming effects were constrained by end-state comfort and prime relevance to the grasping task.
Conclusions:
- Memory effects on real-time visuomotor control are influenced by end-state comfort and prime relevance.
- The interaction between the ventral and dorsal brain pathways in visuomotor control appears to be task-specific.

45.7K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

01:11Sensory Perception: Organization of the Somatosensory System
12.6K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

01:14Sensory Memory
937
Sensory memory captures information from the environment in its original form for a very brief duration, just long enough to be exposed to visual, auditory, and other senses. This type of memory is detailed and rich but quickly lost unless certain strategies are employed to transfer it into short-term or long-term memory. Sensory information is continuously bombarding the human brain, yet only a small fraction is absorbed, as most of it does not significantly impact daily life. For instance,...

01:26Higher Mental Functions of Brain: Learning and Memory
2.3K
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

01:19Understanding Memory
1.8K
Memory is the retention of information or experiences over time, facilitated through three main processes: encoding, storage, and retrieval. Encoding is the process of inputting information into the memory system. For instance, when listening to a lecture, watching a play, reading a book, or having a conversation, the brain is actively encoding information. This initial stage involves transforming sensory input into a form that can be processed and stored by the brain. Various factors, such as...

4.7K
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...
